1.Pneumococcal Cerebrospinal Meningitis: A Rare Complication of Pediatric Temporal Bone Fracture
Keimyung Medical Journal 2023;42(2):118-122
Meningitis is a rare and potentially serious complication in children with temporal bone fractures. We present an unusual case of a 7-year-old girl with pneumococcal meningitis complicated by cerebrospinal fluid (CSF) leakage following transverse fracture in the left temporal bone. She had an otorrhea resolved spontaneously in the early stage of hospitalization. At 4 days post-discharge, the patient returned with headache, fever, neck stiffness, voiding difficulty, and bilateral abducens nerve palsy. Magnetic resonance images demonstrated an intense uniform contrast enhancement in the cerebral cisterns and the sacral nerve roots. Laboratory analysis and culture diagnosed meningitis caused by Streptococcus pneumonia. She was discharged home after getting intravenous ceftriaxone for 5 weeks. Follow-up for the patient required constant vigilance and included a multidisciplinary approach. At 7 months after head trauma, the child was well with no neurological and auditory deficits. This case illustrates a previously unreported complication in pediatric patient of temporal bone fracture associated with CSF otorrhea.
2.Treatment of Primary Cerebral Ventricular Abscess: Use of Dual Catheters and Ommaya Reservoir
Keimyung Medical Journal 2023;42(2):123-127
An isolated ventricular abscess is a rare event, and its treatment is a real challenge. We report such case in a 52-year-old man that was successfully managed with aid of occipital approach and ventricular access device. This patient presented with the chief complaint of headache and fever of 3-day duration. Magnetic resonance imaging showed fluid-filled layering within the posterior horns of the lateral ventricle without contrast enhancement. Blood test and cerebrospinal fluid analysis was consistent with acute bacterial ventriculitis. Using stereotactic technique guided by electromagnetic navigation, the occipital horns were bilaterally targeted and catheterized, and then the abscess and debris was evacuated. The Ommaya reservoir implanted at the left entry was intermittently punctured for preventing the recollection. The pus culture was positive for Streptococcus pneumoniae. He received an antibiotic therapy and the reservoir aspiration leading to rapid recovery and remission of clinical manifestations. There was no evidence of the recurrence within the ventricles on follow-up scans after discharging. This modification, occipital approach and reservoir placement, is effective treatment for improving the cure rate in the selected cases with intraventricular cerebral empyema.

PURPOSE: This is a clinical study to evaluate the efficacy and adverse reactions of deflazacort as adjunctive therapy in childhood intractable atonic seizure including Lennox- Gastaut syndrome. METHODS: This is a clinical prospective, add-on, and open-label study performed for 6 months from Jun. 2000 to Dec. 2000 at the pediatric neurology clinic of Severance Hospital. Subjects were selected according to the following criteria, 1) Patients were diagosed as refractory atonic seizure disorder including Lennox-Gastaut syndrome during more than 6 months, 2) Patients had been on maximal doses of at least 2 anticonvulants including sodium valproate and clonazepam or clobazam. We observed seizure frequency of 4 weeks and 24 week medication period as well as adverse reactions every 4 weeks. Those data were analysed primarily for median seizure frequency reduction rate and other efficacy variables such as responder rate with frequency reduction more than 50% and seizure free rate. We also compared the clinical aspects between responder and non responder group. RESULTS: 48 patients were evaluated for efficacy and adverse reactions. Median seizure frequency reduction rate was 42.7%, responders were 22 patients(45.8%) and seizure free patients were 4(8.3%). In Lennox-Gastaut syndrome, median seizure frequency reduction rate was 48.9% and in atonic seizure only 39.3%. However, there were no statistically significant differences in efficacy. We compared clinical aspects between respoder and non responder groups, but couldn't find any difference. The number of patients manifesting adverse reactions was 20(41.6%) in an descending order of frequency, weight gain in 16 patients(33.3%), and irritability in 4 patients(8.3%). CONCLUSION: Deflazacort is believed to be an effective and safe anticonvulsant when used as adjunctive therapy for atonic seizure including Lennox-Gastaut syndrome. However, long term follow up is required to evaluate relapse rate and its adverse reactions.

Keimyung Medical Journal 2023;42(2):114-117
Leigh syndrome is a rare progressive neurodegenerative mitochondrial disorder. Over 75 pathogenic mutations have been identified in both the mitochondrial and nuclear genomes. Leigh syndrome can be diagnosed based on clinical manifestations, physical and biochemical examinations, and brain magnetic resonance imaging results. Patients with Leigh syndrome classically present in early childhood with developmental regression, ataxia, and hypotonia with subsequent respiratory and brainstem dysfunction. However, the clinical course of Leigh syndrome is heterogeneous with significant differences in age of onset, symptom severity and prognosis. Here, we report a case of Leigh syndrome with cardiac arrest as initial presentation, and identified the novel mutation of NDUFS1 gene.

Purpose:
We report a diagnosis of Moyamoya disease based on brain magnetic resonance imaging (MRI) and brain magnetic resonance angiography (MRA) performed in a child diagnosed with morning glory syndrome.Case summary: A 6-year-old boy visited the hospital with a chief complaint of exodeviation of his left eye that started at 1 year of age. The corrected visual acuity was 20/30 in the right eye and 20/400 in the left. The Krimsky test showed exotropia of 35 prism diopters (PD) for near vision and 30 PD for distance. Fundus photography showed an enlarged optic disc with funnel-shaped excavation in the left eye. With a diagnosis of morning glory syndrome accompanied by exotropia, the patient underwent brain MRI and brain MRA. The patient had no neurological symptoms such as headache and muscle weakness. Moyamoya disease was diagnosed, as brain MRI and MRA showed tiny tortuous vessels forming collateral vessels from the lenticulostriatal arteries, left posterior cerebral artery, and left middle meningeal artery, which originated from the external carotid artery.
Conclusions
Moyamoya disease can occur in children with morning glory disease. Brain MRI and MRA can help to diagnose Moyamoya disease. Caution is needed because transient ischemic attack, cerebral infarction, and cerebral hemorrhage may occur in patients with Moyamoya disease.

Purpose:
Temporal lobe resection can be categorized as either temporal lobe epilepsy (TLE), which involves cortical resection confined to the temporal lobe, or temporal plus epilepsy (TPE), which entails temporal resection along with involvement of additional extratemporal regions. We compared these forms within a pediatric population.
Methods:
We identified 136 patients who underwent temporal resection over a 17-year period and investigated the differences in the clinical profiles and seizure outcomes between TLE and TPE.
Results:
Of the total sample, 110 patients (80.9%) presented with TLE and 26 (19.1%) with TPE. Significant differences were observed between the groups in age at seizure onset (TLE: 6.3 years, TPE: 0.9 years; P=0.001), age at epilepsy surgery (TLE: 14.2 years, TPE: 9.2 years; P=0.002), the proportion of patients with a history of infantile epileptic spasm syndrome (IESS) (TLE: 6 [5.5%], TPE: 8 [30.3%]; P<0.001), electroclinical presentation with IESS or Lennox-Gastaut syndrome (LGS) (TLE: 11 [10.0%], TPE: 13 [50.0%]; P<0.001), the presence of focal temporal hypometabolism on positron emission tomography (TLE: 74 [68.5%], TPE: 11 [44.0%], P=0.021), and the use of intracranial electroencephalogram monitoring (TLE: 58 [52.7%], TPE: 21 [80.8%]; P=0.009). Furthermore, multivariate analysis identified the epileptic presentation of IESS or LGS as a significant predictor of TPE (P=0.049). The rates of seizure outcomes of International League Against Epilepsy class 1–3 at 1 year of follow-up were 83.8% for the entire cohort, 89.1% for TLE, and 61.5% for TPE (P=0.002).
Conclusion
TPE appears to represent a substantial subset of pediatric temporal resections. The variation in seizure outcomes between groups underscores the importance of predicting TPE in advance, with implications for effective treatment planning.

PURPOSE: To evaluate the recovery of continence after robot-assisted laparoscopic prostatectomy (RALP) and open radical retropubic prostatectomy (RRP). MATERIALS AND METHODS: We identified 258 patients who underwent surgery by a single surgeon to treat localized prostate cancer. The patients were divided into two groups according to operative method. In group 1, 146 consecutive patients underwent RALP, and in group 2, 112 patients underwent RRP. To compare the interval until the return of urinary continence between the two groups, we used the Kaplan-Meier method and the log-rank test and Cox proportional hazard regression analyses. RESULTS: Differences between the two groups were found in mean estimated blood loss (EBL; p<0.001) and the rate of nerve sparing (p=0.004). When continence was defined as the use of 0 to 1 pad per day, 100% of group 1 and 98.2% of group 2 reported continence at 12 months (p=0.189). When continence was defined as no pad use, however, there was a significant difference between the two groups at 12 months: group 1, 95.7%, and group 2, 70.7% (p<0.001). The factors affecting time until no pad use in the univariate analysis with a Cox proportional hazards model were operation method, age, neurovascular bundle saving, membranous urethral length (MUL), EBL, and apical shape. In the multivariate analysis, only operation method, age, and MUL retained significance. CONCLUSIONS: Our study suggests that RALP is an independent factor for the recovery of continence and that RALP has advantages for postoperative continence recovery and the quality of continence compared with RRP.
